Research abstract
DEVELOPMENT IS PROPOSED OF AN IMPROVED TYPE OF 400 HZ LINE VOLTAGE REGULATOR (LVR) THAT INHERENTLY PROVIDES LOW-DISTORTION OUTPUT VOLTAGE WITH NON-LINEAR LOADS WITH DISTORTED INPUT VOLTAGE. REGULATION IS ACCOMPLISHED BY ALTERNATELY SWITCHING AT HIGH FREQUENCY A BOOST OR A BUCKTRANSFORMER SECONDARY WINDING IN SERIES BETWEEN THE LVR INPUT AND OUTPUT. THE LVR FUNCTIONS AS A VARIABLE-RATIO TRANSFORMER WITH OUTPUT-TO-INPUT RATIO AUTOMATICALLY CONTROLLED BY FEEDBACK TO MAINTAIN THE DESIRED INSTANTANEOUS OUTPUT VOLTAGE WAVEFORM. OPEN LOOP GAIN OF THE VOLTAGE REGULATOR IS SUBSTANTIAL FOR FREQUENCIES UP TO 5,200 HZ. CONSEQUENTLY, FEEDBACK ACTION REDUCES OUTPUT
